FIELD OF THE INVENTION

The present invention relates to a class of thiazolidinone derivativesas anandamide cellular uptake inhibitors and their use in the treatmentof psychiatric or neurological disorders and inflammation, in particularneuroinflammation.

BACKGROUND OF THE INVENTION

The endocannabinoid system (ECS) is a lipid signaling system comprisingendocannabinoids (ECs), which are lipids derived from arachidonic acid,the G-protein-coupled cannabinoid receptors CB1 and CB2, as well asseveral other actual and potential physiological targets involved in thesynthesis, transport and degradation of ECs. The major ECs are2-arachidonoylglycerol (2-AG) and N-arachidonoyl ethanolamide (AEA;anandamide) which modulate synaptic transmission by retrograde signalingvia CB1 receptors and exert potent immunomodulatory effects via both CB1and CB2 receptors. The ECS has been implicated in physiological andpathophysiological conditions including inflammation, pain, psychiatricdisorders and metabolic reprogramming. The ECS provides a primaryon-demand protection system against acute excitotoxicity in the centralnervous system (CNS) (Marsicano et al., 2003, Science, 302, 84-8.)

Therapeutic strategies within the ECS include the use of cannabinoidreceptor agonists and antagonists, blockage of hydrolytic enzymesdegrading ECs, such as fatty acid amide hydrolase (FAAH) andmonoacylglycerol lipase (MAGL), as well as inhibition of EC cellmembrane trafficking. Although so far no membrane protein for ECtransport has been identified, several lines of evidence suggest afacilitated membrane transport involving both membrane and cytoplasmictargets (Chicca et al., 2012, J Biol Chem. 287, 36944-67; Fowler C J.,2013, FEBS J., 280:1895-904). The movement of AEA across the cell isaffected by the concentration gradient enhanced by rapid intracellularhydrolysis of AEA catalyzed by FAAH. Therefore, FAAH plays a key role inAEA cellular uptake by generating an inward concentration gradient forAEA, which is the major driving force for its cellular uptake.

Using the commercially available AEA uptake inhibitors UCM707, OMDM-2and LY2183240 evidence for bidirectional transport of both AEA and 2-AGacross cell membranes, as well as a common mechanism of cellularmembrane transport for all arachidonate-based ECs was recently provided(Chicca et al., 2012, J Biol Chem. 287, 36944-67). Since all of theavailable inhibitors are only moderately potent and show low selectivitytowards AEA transport inhibition over FAAH inhibition or othercytoplasmic targets, investigations of the mechanisms of AEA and 2-AGcellular uptake are hampered by a lack of adequate tools. As indicatedby a recent study (Nicolussi et al., Pharmacol Res., 2014,80:52-65), theCNS pharmacology of inhibitors of endocannabinoid breakdown andinhibitors of endocannabinoid membrane transport is distinctly differentand that inhibition of FAAH and AEA cellular uptake, respectively, canbe independent from each other. Prior art has shown the use ofDodeca-2E,4E-diene amides as specific AEA cellular uptake inhibitors asanti-inflammatory agents in skin (WO 2010136221 A1). The potentialtherapeutic value of specific AEA cellular uptake inhibitors to treatCNS related diseases remains largely unknown. In a murine model ofmultiple sclerosis, the AEA cell membrane transport and FAAH inhibitorUCM707 showed beneficial effects by reducing microglial activation(Ortega-Gutierrez et al., 2005, FASEB J., 19, 1338-40). Using UCM707, itwas shown that an increased AEA tone limits excitotoxicity in vitro andin a model of multiple sclerosis (Loria et al., 2010, Neurobiol Dis.,37,166-76). The non-specific AEA cellular uptake and FAAH inhibitor AM404was shown to reduce the rewarding effects of nicotine andnicotine-induced dopamine elevations in the nucleus accumbens shell inrats (Sherma et al., Br J Pharmacol., 2012, 165, 2539-48). Thenon-specific AEA cell membrane transport inhibitor VDM-11 was shown tomodulate sleep and c-Fos expression in the rat brain (Murillo-Rodriguezet al., Neuroscience, 2008, 157, 1-11). The administration of AEA cellmembrane transport inhibitors OMDM-2 or VDM-11 was shown to promotesleep and decreases extracellular levels of dopamine in rats(Murillo-Rodriguez et al., Physiol Behay. 2013, 109, 88-95). UCM707 wasshown to behave as a symptom control agent in models of Huntington'sdisease and multiple sclerosis, but failed to delay/arrest theprogression of different motor-related disorders (de Lago et al., EurNeuropsychopharmacol., 2006, 16, 7-18). As shown by a study using UCM707and AM404, AEA transport inhibitors may have potential in the treatmentof painful diabetic neuropathy (Hasanein and Soltani, 2009, Clin ExpPharmacol Physiol. 36, 1127-31). Targeting fatty acid binding protein(FABP) intracellular AEA carriers has recently been suggested to be astrategy to generate anti-inflammatory and anti-nociceptive drugs(Berger et al., 2012, PLoS One., 7(12):e50968.). However, thepharmacology between the inhibition of AEA cell membrane transport andthe inhibition of cytoplasmic carriers is expected to be different, asexemplified by the fact that FABPS inhibitors do apparently not show thesame degree of cannabimimetic effects observed with the potent AEA cellmembrane transport inhibitor guineensine (Kaczocha et al., PLoS One.2014, 9(4):e94200; Nicolussi et al., 2014, Pharmacol Res., 80, 52-65).

Overall, there is a need for novel inhibitors of AEA cell membranetransport with superior specificity and potency to address CNS andinflammation related diseases involving aberrant endocannabinoid tone orin which AEA cellular uptake inhibition can target pathophysiologicalconditions. Given the fact that AEA and other endocannabinoids areinvolved in both synaptic processes via retrograde signaling andimmunomodulatory processes, specific inhibitors of AEA cell membranetransport are expected to exert therapeutic effects in neuropsychiatricdiseases involving neuroinflammation. When the degradation of AEA andother endocannabinoids is blocked, for example by covalent inhibition ofFAAH, the resulting intracellular accumulation of AEA (Chicca et al.,2012, J Biol Chem., 287, 36944-67) is expected to potentially also haveproinflammatory effects via oxygenation of AEA and possibly otherendocannabinoids by cyclooxygenase-2 (discussed in Chicca et al, 2014,ACS Chem Biol, http://pubs.acs.org/doi/abs/10.1021/cb500177c).Therefore, the inhibition of degradation of AEA and the inhibition ofcell membrane transport are distinct pharmacological interventions.Moreover, specific inhibition of AEA cell membrane transport, unlikeinhibition of FAAH or cytoplasmic carriers, is expected todifferentially modulate the AEA tone without leading to activation ofTRPV1 channels via intracellular AEA accumulation.

Our attention, therefore, is focused on the identification of new classof molecules able to specifically inhibit AEA cellular uptake that donot affect hydrolytic enzymes, such as the serine hydrolase FAAH. Weshow that these compounds trigger cannabimimetic behavioral effects andinhibit inflammation, in particular neuroinflammation.

The present invention relates to thiazolidinone derivatives and theiruse for the treatment of psychiatric or neurological disorders andinflammation, in particular neuroinflammation. The use of the compoundsof the invention in a method for treatment of psychiatric orneurological disorders is related to attenuation of neuroinflammationand neuronal retrograde signaling mediated via AEA and otherendocannabinoids. In example, such diseases include multiple sclerosis,epilepsy, Alzheimers disease, bipolar diseases, schizophrenia, sleepingdisorders, and spinal cord injury (Ashton and Moore, Acta PsychiatrScand. 2011, 124, 250-61.; Aso and Ferrer I, Front Pharmacol., 2014, 5,37; Correa et al. Vitam Horm. 2009, 81, 207-30; Hofmann and Frazier, ExpNeurol. 2013, 244, 43-50; Pacher et al., Pharmacol Rev., 2006, 58,389-462).

General Methods and Materials

Compounds and chemicals were of purest possible grade. Anandamide (AEA),(R)—N-(1-(4-hydroxyphenyl)-2-hydroxyethyl)oleamide (OMDM-2),N-(3-furanylmethyl)-(5Z,8Z,11Z,14Z)-eicosatetraenamide (UCM707),[ethanolamine-1-3N-AEA (60 Ci/mmol) was purchased from AmericanRadiolabeled Chemicals. Albumin from bovine serum essentially fatty acidfree (BSA) (A7030), fetal bovine serum (F7524), RPMI-1640 were purchasedfrom Sigma-Aldrich, Germany. AquaSil™ siliconizing fluid was purchasedfrom Thermo Scientific.

[³H]-AEA Cellular Uptake

Screening for AEA cellular uptake inhibition was performed in asemi-automated procedure: Pipetting and washing steps were performed bya Biomek3000 laboratory workstation. First, required amounts of U937cells were centrifuged at 100×g for 5 min and resuspended in RPMI (37°C.) to a final concentration of 2×10⁶ cells/mL. Then, 250 μL of cellsuspension (0.5×10⁶ cells per sample) were transferred into AquaSil™silanized glass vials (Chromacol 1.1-MTV) in 96-well format. Afteraddition of 5 μL vehicle (DMSO) or compounds the cells were incubated at37° C. for 15 min. As positive controls OMDM-2 and UCM707 were used at10 pM in each run. The ETI-T compounds were measured at up to 7concentrations in triplicates from 100 pM-100 μM. After pre-incubation,a mixture of 0.5 nM[ethanolamine-1-³N-AEA, (60 Ci/mmol) and 99.5 nM ofcold AEA (final 100 nM) was added and samples were incubated at 37° C.for another 15 min. The reaction was stopped by rapid filtration over

UniFilter-96 GF/C filters (PerkinElmer) pre-soaked with PBS 0.25% BSA.Cells were washed three times with 100 μL ice-cold PBS buffer containing1% fatty acid free BSA. After drying, 45 μL MicroScint 20 scintillationcocktail (Perkin Elmer, Waltham, Mass., US) was added to the wells andthe plate was sealed. Radioactivity was measured by liquid scintillationcounting on a PerkinElmer Wallac Trilux MicroBeta 1450 during 2 min.Non-specific binding of [³H]AEA (100 nM) to the glass vials was neverhigher than 10%. IC₅₀ values were calculated by GraphPad® by non-linearregression using the built-in log(inhibitor) vs. response -variableslope (four parameters) function.

FAAH Activity

Hydrolysis of [³H]-AEA by FAAH was determined as previously described incell homogenates of U937 cells (0.18 mg protein) (Omeir et al., 1999,Biochem Biophys Res Commun, 264, 316-20; Mor et al., 2004, J Med Chem,47, 4998-5008). Protein amounts of cell homogenates corresponded to0.5×10⁶ cells (U937), to assure best possible comparability of IC₅₀values as used for the AEA cellular uptake assays. URB597 was used aspositive control. Protein quantification was performed using a BCA assay(Thermo Scientific). Enzyme activity was assessed by addition of vehicleor compounds in 10 μL DMSO to 490 μL homogenate in 10 mM Tris HCl, 1 mMEDTA, 0.1% (w/v) BSA fatty acid free, pH=8 and incubation for 15 min at37° C. After, a mixture of AEA plus [ethanolamine-1-³H]-AEA (0.5 nM) atfinal 100 nM was added to the homogenates and incubated for 15 min at37° C. The reaction was stopped by addition of 1 mL ice-cold CHCl₃:MeOH(1:1) followed by vigorous vortexing. Phase separation was achieved bycentrifugation at 10′000×g at 4° C. for 10 min. Radioactivity of theseparated aqueous phase (upper phase) containing [³H-ethanolamine] or[³H-glycerol] was measured by liquid scintillation counting on aTri-Carb 2100 TR liquid scintillation analyzer after addition of 3.5 mLUltima Gold scintillation cocktail (PerkinElmer Life Sciences). Resultsare expressed as hydrolysis of tritium substrate in percent of vehicletreated control. IC₅₀ values were calculated by GraphPad®. Data arereported as means of n=3 independent experiments performed intriplicates.

Radioligand CB Receptor Binding

Binding properties of ETI-T compounds to hCB1 or hCB2 receptors wereperformed as previously reported in a [³H]-CP55,940 displacement assay(Gertsch et al., 2008, Proc Natl Acad Sci 105, 9099-104). WIN 55,212-2was used as positive control. In brief, 20 μg protein of CHO-K1 hCB₁ orhCB₂ membrane preparations were thawed on ice and resuspended in a finalvolume of 500 μL binding buffer (50 mM Tris-HCl, 2.5 mM EDTA, 5 mMMgCl2, 0.5% fatty acid free BSA, pH 7.4) in silanized glass vials.[³]-CP55,940 (168 Ci/mmol) (PerkinElmer, Waltham, Mass., US) was addedto a final concentration of 0.5 nM followed by the addition ofcompetitors or vehicle in 5 μL DMSO. Membrane binding was equilibratedfor 2 h at room temperature (25° C.). Samples were filter through a 0.1%polyethylenimine pre-soaked UniFilter®-96 GF/B plate (PerkinElmer) andwashed twelve times with 167 μL ice-cold assay-buffer. The plate wasdried, bottom sealed and 45 μL MicroScint 20 scintillation cocktail(PerkinElmer) were added before measured on a PerkinElmer 1450 MicrobetaTRILUX liquid scintillation counter. Unspecific binding was determinedby WIN 55,212-2, 10 pM and subtracted from all values. IC₅₀ values.
